In this study, we compared magnetic resonance arthrography results with hip arthroscopy findings to assess the diagnostic value of this imaging technique in evaluating acetabular labral tears and concurrent articular hip pathology. One hundred one consecutive patients (102 hips) with a clinical diagnosis of acetabular labral tear were assessed using(More)
STUDY DESIGN A retrospective examination of the spine radiographs of 88 asymptomatic adolescents was performed to analyze the indices of regional and segmental sagittal spinal alignment in relation to the sagittal vertical axis as determined by the C7 plumb line. OBJECTIVES To determine the sagittal spinal alignment in asymptomatic adolescents and to(More)
A national quality improvement initiative identifies certain avoidable complications as "never events," and includes venous thromboembolism (VTE). This study examines the incidence and cost of VTE following total knee arthroplasty (TKA) compared to other causes of readmission and the degree to which VTE was preventable. One hundred twenty-one readmissions(More)
The treatment of hip disorders in adolescents and young adults has evolved rapidly during the past decade because of enhanced understanding of prearthritic and early arthritic hip disease combined with improved diagnostic skills, better patient selection criteria, and refinements in alternative surgical procedures. Despite these advancements, the diverse(More)
UNLABELLED Persistent stiffness is an infrequent but notable complication occurring after total knee arthroplasty. A limited approach (soft tissue releases and component retention with tibial insert downsizing) has previously been associated with poor results, although comprehensive revision of both components seems more successful. We retrospectively(More)
BACKGROUND TKA is commonly performed to treat advanced inflammatory and degenerative knee arthritis. With increasing use in younger patients, it is important to define the best practices to enhance clinical performance and implant longevity. QUESTIONS/PURPOSES We systematically reviewed the literature to assess: (1) how TKAs perform in young patients; (2)(More)
Although cross-table lateral (CL) radiographs are frequently used to assess acetabular component anteversion, the reliability of this method has not been established. We compared serial CL radiographs with computed tomography (CT) scans for 98 total hip arthroplasty patients (119 hips) undergoing surveillance of primary or revision total hip arthroplasty.(More)
BACKGROUND The evolution of total hip arthroplasty (THA) generally has led to improved clinical results. However, THA in very young patients historically has been associated with lower survivorship, and it is unclear whether this, or results pertaining to pain and function, has improved with contemporary THA. QUESTIONS/PURPOSES We performed a systematic(More)
Databases are being used to shape health care policy. However, the reliability of coding information entered into the databases may be difficult to validate. In this study, we assess readmission data from an institutional database that identified 1515 readmissions (708 patients) after total hip or total knee arthroplasty during a 5-year interval. After(More)
Haematomas, drainage, and other non-infectious wound complications following total knee replacement (TKR) have been associated with long-term sequelae, in particular, deep infection. However, the impact of these wound complications on clinical outcome is unknown. This study compares results in 15 patients re-admitted for wound complications within 90 days(More)
